[PATCH] fix rs6000 builtin defines for eabi, eabisim, rtems

[Janis Johnson]

This patch fixes mainline C builds for powerpc-eabisim.

Before the change for PowePC bi-arch support the macro CPP_SYSV_SPEC in
config/rs6000/sysv4.h defined _RELOCATABLE, __pic__, and __PIC__ at the
appropriate times.  Those were moved to TARGET_OS_SYSV_CPP_BUILTINS,
which was not included in all of the places where it's needed.  This
patch adds that to TARGET_OS_CPP_BUILTINS for eabi, eabisim, and rtems.

vxworks support doesn't currently set _RELOCATABLE and sets __pic__ and
__PIC__ differently, so it might need to be fixed as well.

Tested by building powerpc-eabisim, C only (more problems to
investigate!).

OK for mainline?
